a spindle 70, carried in a pair of Wings Z, formed 1. A shearing devicecomprising a lever fulin one with a lever m, fulcrumed upon a pincruined to a part stationary relatively to said '11, set in the prongsof the fork h. A small lever; a stationary shearing edge; a bladepivoted upon said lever and having two cut ting edges; and means forautomatically rotating said blade to have its cutting edges alternatelycoincide with said stationary slIearin said lever; and means forautomatically rotating said blade to have its edges alternately coincidewith the respective stationary shearing edges, as the lever is moved.

3. A trimming device consisting of a longitudinally-slotted leverfulcrnmed at one end to a part stationary relatively to said lever,

and slotted in line with said lever to provideshearing edges; a bladehaving oppositelyfacing cutting edges and pivoted in the slot in saidlever; a ratchet-wheel on one end of said spindle; a rack pivotallyconnected to said stationary part and yieldingly engaging saidratchet-wheel; a ratchet-wheel mounted upon the opposite end of saidspindle; a spring-pawl carried by said lever and engaging the teeth ofsaid last-mentioned ratchetwheel; a latch carried by the lever andengaging perforations in said blade; and a wedgeshaped projection uponsaid stationary part to disengage said latch from the blade when thelever is moved in one direction, substantially as described and for thepurpose set forth.

In testimony whereof We have affixed our signatures in presence ofwitnesses.
